Power distribution in data centers:A complete and integrated power distribution portfolio

Measuring equipment, visualization software, selectiveswitching, control and regulation integrated in buildingmanagement systems lead to lower energy costs.

Lower energy costs

Due to metering and monitoring of power and coolingsystems, paired with the transmission of switching statesand detection of tripped protection devices, the rightamount of energy is supplied at the right time which leadsto an optimized energy consumption.

Lower operating costs

Through the possibility of renewable energy sources andmore efficient power distribution equipment, the output ofCO2 emissions can be significantly reduced.

Reduced CO2 emissions

The modular structure of low and medium voltage powerdistribution appliances allow for easy expansion andmodification in any data center facility.

Our complete range for power distribution (1)

Energy automationEnergy automation with the SICAM PAS(Power Automation System) substationcontrol system meets high requirementsin terms of immunity, reliability, isolation,real-time resolution and secure datatransmission.SICAM PAS is an open system and is thefirst to support the new IEC 61850 ascommunication standard between fieldand substation level.

Medium-voltage switchgearThe supply network operator feedsmedium voltage to the medium-voltageswitchgear located in the basement.This ensures safe and cost-efficient powerdistribution in the building and distributespower to the transformer. Siemens offersgas- and air-insulated switchgear for allkinds of requirements and applications.They are type-tested in accordance withIEC 62271-200.

Protection and bay control units protectthe primary equipment by fast switching.They protect the power system, thegenerators and machines by selectivefault tripping in the event of a fault. Thecomplete SIPROTEC product family forline, motor and generator protection offersyou an integrated solution with extensiveprotection and control functionality as wellas extremely flexible communicationoptions.

SIPROTEC protection technologyTransformers convert medium voltage tothe low voltage required to operate thepower loads. GEAFOL trans-formers areflame-retardant and self-extinguishingand do not give of f any toxic gases incase of fire. This makes them particularlysuitable for use where distributiontransformers in the immediate vicinity ofhuman beings must guarantee maximumsafety.

SIVACON busbar trunking systemsElectrical power is distributed via cablesor busbar trunking systems. Thanks totheir high short-circuit strength andminimal fire load, busbar trunking systemsare considerably safer than cables. If theuse of space changes, flexiblemodifications and expansions duringoperation are possible.

The low-voltage switchboardsSIVACON S8 provide maximum safety forhuman beings and equipment thanks todesign verification by verification testaccording to IEC 61439-2 and an arc faulttest. In addition, a type tested connectionto the busbar trunking systems isavailable.

SIVACON switchboards

ALPHA distribution board systemsALPHA distribution boards as small, wallor floor-mounted distribution boards offerhighly reliable and standards-compatiblequality and safety in accordance with therelevant standards. They pass the currenton to rooms and manufacturing sections.

We offer a comprehensive protectionconcept with a broad, coordinated rangeof devices for line protection, personaland fire protection, lightning current andovervoltage protection, and device andsystem protection. The communication-capable air circuit breakers 3WL and themolded-case circuit breakers 3VLtransmit important information fordiagnostics, fault, maintenance or costcenter management to a central controlcenter via standardized bus systems.

SENTRON protection devices

SENTRON switching devicesManual SENTRON switching devices canbe reliably used in electrical systems thatare switched on and off manually. Wheresystems and loads are controlled bymeans of electrical signals, electronicswitching devices such as remote controlswitches 5TT4, switching relays or Instacontactors 5TT5 are used.

The PAC power monitoring devicesmeasure the energy values for the infeed,outgoing feeders or individual loadsprecisely, reliably and in a reproduciblemanner. They also provide importantmeasured values for assessing thecondition of the system and the quality ofthe network.

SENTRON measuring devices

SENTRON monitoring devicesHigh plant availability and low down-timeshelp keep costs low. The residual currentmonitors 5SV8 help detect and remedyfaults before the plant is shut down.The automatic transfer switch 3KC9increases the reliability of the powersupply via automatic or manual switchingbetween two power supply systems. TheGSM alarm module 5TT7 enables faultsand shutdowns to be reported andcommands to be sent from any-where.

Energy management systemThe powermanager software monitors,processes and archives measured valuesand displays them in a clearly laid-outmanner. The data is provided bycommunication-capable low-voltagepower distribution components such asPAC power monitoring devices and3WL/3VL circuit breakers. Savingspotentials can be identified and theavailability of energy ensured due to thetransparency in power distribution that isgained with the aforementionedtechnology.

Energy management for industrial applications

The SIMATIC powerrate add-on forWinCC and PCS 7 as well as device-specific block libraries make it possible tointegrate various energy managementfunctions such as a structuredvisualization and archiving ofconsumption data, cost center allocationor load management as well aslow-voltage power distributioncomponents into the systems of theprocess and manufacturing industry.

Power supply concepts for data centers:Busbar trunking systems SIVACON 8PS vs. cables

Feature Busbars CablesDesign-verified switchboard andcontrol gear assemblies

High operational reliability and short-circuitstrength due to design-verification acc.IEC (61439-1/-6)

The operational reliability depends upon thequality of workmanship

Fire load very low very high, up to ten times higher than busbarsolution

PVC / Halogen free In principle, busbar trunking units arehalogen free

Standard wires are not PVC- or halogen-free;halogen-free wires are extremely expensive

Flexibility in the event of changes,expansions or the relocation ofload focal points

Very high flexibility thanks to variable tap-offunits, which can be changed/ replaced evenwhilst energised no downtimes

New installation usually required or highexpense due to new splicings, clampingpoints, sleeving, parallel wires, etc.;high downtimes

Space requirement Very low due to compact design along thecontours of the building; clear currentcarrying capacity

Enormously high due to bending radii, layingmethod, cable accumulation and currentcarrying capacity

Space requirement for low-voltagemain power distribution

Lower space requirement because switchingand protective devices can be arrangeddecentrally in the tap-off units

High space requirement

Troubleshooting and faultelimination

Simple and quick due to clear installation,and protective devices close to consumers

Very time-consuming due to complicatedinstallation. Protective devices a long wayfrom consumers

Electromagnetic susceptibility Low susceptibility due to favorable conductorarrangement

Relatively high with standard cables; nodefined conductor arrangement

Mounting time Short mounting times Long mounting times; high personnel costwith low turnover; low value added

Our contribution to more energy efficiency

Did you know that

40% of the entire life cyclecosts of a building aregenerated by electricalenergy?

Data centers consumesaround 2% of powerin the world?

from 2020, all newbuildings in the EU willhave to be "Nearly-zeroenergy buildings"?

Our products and systems allow effective energy managementand optimization of energy consumption thanks to an integrated concept with communication-capable products to

record, report, evaluate and optimize energy flow a professional energy management system for significant cost
